Yes I have put the input into a 2-D array but to go about printing the elements of the array different to how it was entered into the array, would I be using some sort of loop?

The point of each method is changing the inputted string so that the string is either encrypted or decrypted. If I were inside the encrypt method and I read in abcd, how would I make the output be...

Examples I need to test are...

a is [0][0], b is [0][1], c is [1][0], d is [1][1]

and I wanted to make it so it becomes:

a is [0][0], c is [0][1], b is [1][0], d is [1][1]

I guess by changing the position of the letters...

Hi guys,

I have for example a 2-D array with a=[0,0] b=[0,1], c=[1,0] and d=[1,1]
a b
c d

So for my array I am reading in the letters from left to right, row by row and now I wanted to...

a b
c d
We read the elements left to right,...
